Because a realistic length of travel time in the Star Wars universe would mean it would take hours, days or even weeks to travel from planet to planet (asuming we're talking about hyperspace travel).
Ithorians seem very unlikely at this point as Bioware have stated that they are only interested in releasing races that are humanoid, can fit into the already established body types and armor and can speak basic due to everything being voice acted.
I have this problem every now and then on EVERY game. It's most likely keyboard or mouse related but it's not game breaking enough for me to be bothered doing anything about it.
First of all demanding something just makes you look like a self-important whiner. Second of all if you bothered to do some research you would know that Bioware have stated that it is a feature that they would like to add in the future but it's not at the top of their priorities.
All class quests are beatable, it's just a matter of finding the right tactics (example: interrupting certain abilities, etc).
As previously stated if you want to easy-mode it, simply ask a friend, guildie or stranger to assist you.
I agree 100%. I was rather disappointed when I first started playing to find out there weren't any options to create a more middle-aged looking character, and that twi'leks and cyborgs only have 3 face options.
Korriban (Vette), Hutta (that guy in the Evokii camp), Yadira Ban (Black Talon boss), pretty sure the crazy guy under corruscant was a basic-speaking Twi'lek as well. To name a few.
